Description/Abstract

In this paper, two-ﬂuid modelling is used to model a bubbling ﬂuidised bed gasiﬁer (BFBG) introducing two solid phases namely, sand and coal. The devolatilisation model and heterogeneous reactions are implemented and the gases produced are compared to experimental results, which shows a good agreement. The production of fuel gases is strongly inﬂuenced by the distribution of the solid phases, which requires accurate modelling of the multiphases involved
